A YouTuber has spotted a mysterious object on Nasa's feed from the International Space Station.
YouTuber Streetcap1 uploaded screenshots and clips from the Nasa livestream, with what looks like two UFOs flying above the earth. There are also two objects seen below it.
Conspiracy theorists believe the stream was altered in an attempt to hide an "alien megaship," according to RT, as the footage is said to fade out after the object appeared.
The YouTuber said: “I thought I was seeing things. I had to be quick. The dimming at the end was sudden and my guess is they [NASA] turned down the brightness a little.”
However, other people are not impressed by the video and believe it is a hoax by the YouTuber, claiming it only shows lens reflections.
